The heads are 462624. I wanted to find out if there is anything special about the heads. I know there not hump heads, but are they better than the average head...... and what size engine it is...year ect.

Not sure if you have all the numbers you need, here's where allot of us get the correct info for blocks & heads.

I went to this site:
http://www.nastyz28.com/chevy-engine-code-stampings.php

If i'm reading it right it looks like a 1981 engine V= flint 10=october 10= 10th day ZDD=1981 190 hp manual trans 4bbl vette?????????????????????
There is a picture near the bottom that looks like where I got my number from. In the picture it has a number that starts with the V like mine....
What I'm confused about is
On the back of the block on the drivers side there is a place that looks like a vin number stamped on it it would decode it as a 72 1/2 ton pickup balitmore IF it is really a vin number for our trucks stamped ino the back of the block. There is a smooth area kinda oval maybe 2" long with the cce142b....number stamped in it.

The heads look like 75-86 350/400 76cc chamber. Is a 76cc chamber good?

The dd on the block corresponds to a 1969 307 2bbl 200hp.

I see but what would the Z be for? and the heads are for a 75-86?
I was looking at decoding the entire thing...
V.....Flint
10....october
10....10th day
the rest is ZDD??
I see ZDD as 81 350 M/T 190 hp vette?
That would go along with the heads being 1975-1986
I'm only going by what the website looks like so I'm not sure..
would there be any other place on the block that would tell me the date? So I can see if it's dated around 69 or 81?
Over the years the heads could have been changed?
